WASH-BOILER.

SPECIFICATION forming part of Letters Patent No. 231,584, dated August 24, 1880,

Application iilod June 21, 1880.

To all whom it may concern Be it" known that we, FREDERICK J. JACK- SON and W ILLIAM Il. WRIGHT, citizens of the United States,residing, respectivcl y, at Tarrytown and Saugerties, in the State of New York, have jointly invented a new and useful Improvement in lash-Boilers, of which the following is a specification.

This invention relates to what are known as fountain wash-boilers; and it consists in a novel fountain device of simplicity and efficiency, operating by the expansion of heated water between an inclined shelf and the bottom of the boiler-pit and between said shelf and a top plate; also, in a novel form of inlet and a novel form of outlet for a fountain-chamher at or within the bottom of a boiler and its pit, as hereinafter more fully set forth.

In the accompanying drawings, which form a part of this specification, Figure 1 is a plan view of a wash-boiler bottom illustrating this invention. Fig. 2 is a like view of the same without its top plate. Fig. 3 is a longitudinal section on the line 3 3, Fig. 1, showing the complete device as combined with a boilerbody and with a discharge pipe or neck within the latter; and Fig. 4 is a cross-section on the line 4 4, Fig. 3.

Our wash-boiler may have a body, A, a bot-- tom, B, and a cover, 0, of ordinary make. The bottom B must, however, have a long deep pit, D, adapted to occupy the boiler-hole of a stove or range in customary manner, and to afl'ord space within it for our principal attachment E, which is an inclined plate or shelf extending across the pit D from side to side and longitudinally from one end, which is its highest point, to a point near the opposite end, where a space, 8, is left for the entrance of the Water into the space or fountain-chamber s beneath said shelf.

An outlet-extension, 0, formed on the higher end of the shelf E, projects upward and over the marginal floor of the bottom B, and terminates in aeollar, which receives the discharge pipe or neck a, and locates the latter near the extreme end of the bottom, as shown. The bottom of the elevated outlet beyond the end of the pit is formed, in a simple manner, by said marginal floor, as shown in Figs. 3 and 4..

(No model.)

In use, the entire internal area of the bottom of the pit I) being utilized for heating the water beneath the shelf 1), this water is quickly raised to boiling heat, causing it by its expansion and ebullition to pour through the outlet 0 and neck a upon the articles within the boiler, so as to wash the same by the now well-known process. Said shelf E, forming the single fountain-chamber s, will operate as above described when used alone or exposed, as shown in Fig. 2, and it may be so used with the additions of the customary supporting-rack to prevent choking. The action is, however, rendered greatly more energetic and effective by the addition of a top plate, F, having an inlet or inlets, i, at the end opposite said space 8. A preliminary heating space or chamber, 8, is thus formed above the shelf E, and the water therein receives sufiicient heat through said shelf and through the sides of the pit to expand into the chamber 8 with its temperature already considerably increased, and the inclination of the shelf D prevents rctrogres sion in both chambers.

The inlets t are formed at the sides of the outlet 0 by means of an elevated end of the top plate, F, supported by stud-pins p, which project from the said marginal floor of the bottom 13, as shown in Fig. 2, and form efficient strainers to preclude the entrance of small articles into the fountain-chambers, as shown in Fig. 4.

The shelf E and top plate, F, should be soldered within the pit I) and to the floor of the bottom B, so as to render their edges watertight. Depending projections or beads as at are formed on the top plate to facilitate locating it preliminary to soldering it down.

The bottom B, with the pit l), stud-pins 19, stiffening-ribs r r, and an elevated marginal flange, f, to unite with the body, and the shelt' E, with the outlet 0 thereon, are, by preference, light galvanized-iron castings, but may be made of suitable sheet metal by ordinary processes.

The top plate, F, owing to its simple form, may preferably be made of sheet metal cut and bent to the form shown 5 but it may also be cast, and in either case it may itself be provided with the stud-pins p, or equivalent projeetions; and to facilitate casting it sufficiently light it may be made in two or more sections united by solder.

As thus and in like manner modified in unessential details the attachments E F may be readily fitted to an ordinary wash-boiler bottom having a suitable pit. and they may be further modified byemploying simple inlet and outlet orifices guarded and finished in any preferred manner without materially afi'ecting their operation, as above stated.

We do not, therefore, limit ourselves in these particulars. Our superiorinletand outlet may also be applied in substance to other fountain wash-boiler bottoms.

We do not claim herein, broadly, a washboiler having a pit adapted to project into and fill, or nearly till, the boiler-hole of a stove or range, and provided with a top plate aml a partition or partitions forming fountain -ehamhers, as we intend to claim this in anotherapplieation for patent, which will he filed hereafter.

We claim as new and of our joint invention and desire to protect by Letters Patent- 1. In a wash-boiler, a bottom having a pit provided with an inclined longitudinal shell extending across the pittrom side to side, aml forming a shallow fountain-chambcr immediately above the bottom of the pit, a space for the admission of water to said chamber at the lower end of said shelf, and an outlet for the heated water at the higher end of said shelf, and a top plate forming an inlet or inlets at said higher end only of the shelf for the admission of water to said space, substantially as herein specified, for the purposes set forth.

2. In a wash-boiler, a sunken bottom having afountain-chamber within its pit or depression, and provided with a top plate having an elevated end forming an inlet or inlets to said chamber and supported by stud-pins which form strainers at said inlets, substantially as herein described.

3. In a wash-boiler, a sunken bottom having a fountainchamber formed within its pit or depression, and provided with an elevated outlet projecting over the marginal floor of said bottom, the bottom of said outlet being formed in part by said marginal floor, while the terminal collar of the outlet receives a dischargeneck and locates the latter near the extreme end of the boiler, substantially as herein specilied, for the purposes set forth.
